Photoelectric through-beam turbine flow meter

Abstract

Provided is a photoelectric correlation type turbine flow meter. According to the photoelectric correlation type turbine flow meter, a shell is composed of a fluid guide tube and a data transmitting bin, and the data transmitting bin is connected on the fluid guide tube in a crossing mode and wraps the fluid guide tube from the two sides outside the fluid guide tube to provide a correlation light path needed by photoelectric transmitting and receiving tubes on a transmitting control board; a multifunctional pre-arranged diversion frame, an impeller assembly, a diversion plug assembly and a retainer ring are sequentially assembled from a fluid inlet to a fluid outlet of the fluid guide tube. According to the photoelectric correlation type turbine flow meter, a photoelectric sensing principle is adopted, by means of the correlation light path, the impurity contamination resistance is improved, electromagnetic interference resistance is achieved, the turbine flow meter is overall high in dielectric strength, and the defect that a photoelectric reflection type product is low in signal strength and only can be used for purified water is overcome; by means of a food-grade safe and reliable optical material, contamination of magnetic materials is avoided; by means of highly integrated temperature, conductance, flow velocity and flow sensors, pipelines are greatly simplified, and secondary development difficulty is reduced by means of digital interfaces.

Description

Technical field [0001] The invention relates to a liquid flow meter for comprehensive analysis and measurement of liquids, in particular to a photoelectric through-beam turbine liquid flow meter. Background technique [0002] With the development of modern technologies such as Internet+ and the Internet of Things, more quantitative requirements have been put forward for the traditional water treatment process, such as the temperature, water quality, flow rate and single treatment flow information flowing through a monitoring point of the water treatment system. And tracking the processing capacity of the water treatment system, the deterioration tracking and replacement reminder of key consumables, and the water leakage alarm. In order to achieve these quantitative monitoring purposes, it is generally necessary to use many discrete sensors and perform complex analysis calculations, which not only increases the installation and development workload but also expands the risk of wat...

Problems solved by technology

In order to achieve these quantitative monitoring purposes, it is generally necessary to use many discrete sensors and perform complex analysis and calculations, which not only increases the workload of installation and development, but also increases the risk of water leakage. Some sensors may introduce magnetic materials that are harmful to health due to limited principles.
